Can't build server tests & CliClient

[Agava46]

I can't build an example app on both Linux (Ubuntu 16.04) and OSX (Sierra 10.12.6). The error is quite similar:

Exception in thread "main" java.lang.Error: /tmp/tmp4319878515077409604.c:1:10: fatal error: 'freetype2/freetype/freetype.h' file not found

However, freetype is installed and /usr/include/freetype2/freetype/freetype.h exists.

This is what cmake reports:
